19 Claims.

This-invention relates to machines for use in the manufacture of shoesand is illustrated herein as embodied in a machine for covering heels.

In an application for United States Letters Patent Serial No. 56,739,filed December 30, 1935, in my name, there is. disclosed a machine forapplying a single piece of covering material to the rear and side facesof a heel and forinturning the top, the bottom, and the forwardlyprojecting margins of the cover against the marginal portions of theattaching, the top-lift receiving, and the breast faces of the heel,respectively. In

' order to complete the covering of Cuban heels,

for example, which have been partially covered by the use of theabove-identified machine, it is commonpractice for the operator, aftertrimming the forwardly. projecting portions of the side cover to thedesired widths, to apply the flap to the breast of the heel by hand, themargins of the forwardly projecting portions of the cover being appliedto the median portion of the heel breast in overlapping relation.

It is an object of this invention to provide a machine which may beadvantageously used to trim the forwardly projecting portions of sidecovers of heelsv to the desired widths and to lay such portions uponthebreasts of the heels in overlapping relation. With the above objectsin view and in accordance with a feature of this invention there isprovided in a covering machine means forsupporting a work piece, meansfor trimming the projecting margins of a cover secured .to the workpiece towidths suitable to insure that the margins shall overlap eachother when applied to the work piece,.and means for laying the trimmedmargins in overlapping relation upon the work piece.

=Theinvention is illustrated with reference to a machine constructed andarranged to trim the forwardly projecting portionsofa cover,.which havebeen secured to the side and rear faces of a heel, to desired widths,and to lay the trimmed projecting portions of the cover in overlappingorder to trim the forwardly projectthe median portion of the breast ofthe heel and is yieldingly movable widthwise of the breast. In order tobrace the forwardly projecting portions of the side cover against thecutting pressure of the blade and to lay the forwardly projectingportions upon the heel breast, the machine is provided with a unitmounted for swinging movement about an axis which passes substantiallythrough the center of transverse curvature ofthe breast of thepositioned heel. The unit comprises a pair of anvils which successivelybend the respective forwardly projecting portions of the cover towardthe heel breast and force the margins of the same against the respectivecutting edges thereby to cause the blade to trim the margins topredetermined widths. The unit also comprises a resilient rollpositioned between the anvils for'laying' the forwardly projectingportions of the cover in overlapping relation upon the breast of theheel.

In order to enable the roll to lay the trimmed margins in overlappingrelation upon the median portion of the breast of the heel the bladecarrier is alternately moved by the unit in opposite directionstransversely of the heel breast from its centralized position. The unitis moved toward the heightwise median plane of the heel from one side ofthe heel to trim and to lay one of the forwardly projecting portions ofthe cover and is then swung toward the plane from the other side of theheel to trim and lay the other forwardly projecting portion of thecover. The

amount of overlap of the forwardly projecting forwardly projectingportions of the side cover,

quicker and more uniformly than is possible by the present hand trimmingand laying operation.

,These and other features of the invention, including certain details ofconstructionand combinations of parts, will be describe-d as embodied inan illustrated machine and pointed out in the appended claims.

Fig. 6 shows in perspective a heel which has been covered by the abovementioned machine disclosed in application for United States LettersPatent Serial No. 56,739; and

Fig. '7 shows the heel illustrated in Fig. 6 after the forwardlyprojecting margins of the cover of the heel have been trimmed and havebeen laid upon the breast of the heel.

The illustrated machine is described with reference to laying theforwardly projecting portions 28 of a cover 22 which has been attachedto the rear and side faces of a heel 24 and is commonly known as a sidecover, upon the breast 26 (Figs. 3 and 6) of the heel in overlappingrelation. The side cover 22 may be laid upon the side and rear faces ofthe heel and inturned slightly upon the lateral margins of the top-liftreceiving, the attaching and the breast faces of the heel 24, asillustrated in Fig.

6, by the use of the machine disclosed in the above-mentionedapplication for United States Letters Patent Serial No. 56,739. Thecover is then snipped in the vicinity of the upper and lower breastcorners of the heel to insure that the cover may be laid smoothly uponthe heel.

The forwardly projecting portions of the side cover are applied to thebreast of the heel 24 positioned and clamped in the machine, by a roll28 which is preferably made of resilient material such as rubber and isrotatably supported by a bracket 39 which is screwed to sleeves 32mounted upon a rod 34. Mechanism for positioning and clamping the heelin the machine will later be disclosed in detail. The sleeves 32 may berotated by a hand wheel 36 or may be operated by a crank lever (notshown) driven by a power-operated clutch (not shown) or other suitablemechanism constructed and arranged to produce the desired swingingmovement of the bracket 38. Extending lengthwise of the bracket along.opposite sides respectively of the roll 28 are a pair of anvils 31. 38which may be made of suitable material and are constructed and arrangedto bend the respective forwardly projecting portions 20 of the sidecover toward the heel breast 26 as the bracket 30 is swung toward theheightwise median plane of the positioned heel. The anvils 37, 38 arealso constructed and arranged to engage the cutting edges 43, 4!,respectively, of a cutter or cutting blade 42 supported by a car rier44. The roll 28 and the anvils 31, 38 swing as a unit.

The roll 28 is concave lengthwise in accordance with the heightwisecurvature of the breast 26 of the heel and progressively lays theforwardly projecting portions 20 against the breast, the bracket 36being temporarily stopped when opposing anvils 37, 38 (Fig. 3) haveforced corresponding projecting portions 28 against cutting edges iil,4!, respectively.

The carrier 14 is pinned to the rod 34 and is normally urged to aposition above the median portion of the heel breast 26, as illustratedin Fig. 3, and is swung under pressure of the anvils 38, 3'! inclockwise and counterclockwise directions (Fig. 3), respectively, aftercorresponding projecting portions 283 of the cover have been trimmed. Inorder to cause the carrier 34 normally to assume the centralizedposition illusreceive the plate 54.

trated in Fig. 3 and to permit the same to be swung under pressure ofthe anvils 37, 38, a block 43 (Figs. 1 and 2) is pinned to the shaft 34and engages the upper face of a slide 48 which moves along guides 50screwed to the main frame and is normally forced upwardly by a spring52. When the upper end of the slide 48 and the lower face of the block46 are in surface engagement the carrier 44 is in a centralizedposition.

In order to trim surplus material from the forwardly projecting portions23 of the cover when the margins of the same are forced against thecutting edges 40, 4| by the anvils 31, 38, respectively, the blade 42 ismounted for movement lengthwise of its cutting edges. The blade 42 isguided for movement lengthwise of its cutting edges 40, 4| by a plate 54(Fig. 5) which is positioned between upper and lower carrier portions56, 58, respectively, secured together by screws 60, the blade 42 beingprovided with an elongated slot 62 constructed and arranged to The blade42 is normally moved to a rearward position by a spring 64 (Fig. 2) therespective ends of which engage the carrier 44 and a lug 66 (Fig. 2)screwed to the rear end of the blade 42. Rearward movement of the blade42 under pressure of the spring 64 is limited by engagement of the bladewith the end B! of the plate 54. In order to reciprocate the blade 42against the resistance of the spring 64 there is provided a slide 68(Fig. 2) which is mounted for vertical movement in the frame of themachine and has a cam face '10 formed at its upper end. Upward movementof the slide 68 which is operated by a hand lever 72 causes the cam faceHi to force the blade forwardly. The lateral portions of the cam face 16are slightly rounded to permit the lug 66 to ride up the cam face as thecarrier 44 is moved from a lateral to a central or neutral position.

After the left forwardly projecting portion 20 (Fig. 3) of the sidecover has been trimmed to the proper length the hand wheel 36 is rotatedto swing the roll 28 across the median portion of the breast 28 of theheel 24, thereby to cause the same to lay the margin of the forwardlyprojecting portion of the cover upon the median portion of the heelbreast. It will be noted that the carrier 44 is swung under pressure ofthe anvils 31,

38 in order to permit the roll 28 to move across the median portion ofthe breast 25 of the heel. The blade 40 is spaced from the breast 26 ofthe positioned heel in accordance with the desired amount of overlap ofthe forwardly projecting portions 20 of the side cover.

After the left forwardly projecting portion 20 of the side cover hasbeen laid upon the heel breast, the unit which comprises the bracket 30and the anvils 31, 38, is swung about the rod 34 to the opposite side ofthe carrier 44 in order to lay the right forwardly projecting portion 20(Fig. 3) of the side cover upon the heel breast. During such operationthe anvil 38 forces the margin of the right forwardly projecting portion29 against the cutting edge 4| and after trimming the forwardlyprojecting portion, the margin thereof is laid in overlapping relationwith the first laid margin as the roll 28 moves in a clockwisedirection. The anvil 38 swings the carrier 44 in a clockwise directionagainst the yielding movement of the spring 52 to permit the roll 28 tomove across the median portion of the breast of the heel. The axis ofthe rod 34 passes substantially through the center of transversecurvature of the heel breastZB.

holes or recesses 12 and 14 formed in the attach ing face and thetreadend of the heel, respectively, the jig holes "and 14 of heels ofvarious sizes being located at uniform distances respectively from thebreast 26 of the heel. T The jig holes-12 are shaped to receivecorresponding rounded studs 16 of a gage 18 and the jig hole 14 isshaped-to receive the' rounded end portion 80 of an adjustable screw 82which isv turned to permit the operator to place the heel in the machineand to remove the same therefrom. The positioned heel is securelyclamped in the machine through the provision of a clamp screw 84 whichmay be forced against the attaching faceof the heel.
